With a pair of microprojector earrings and the words "showtime Synergy", Jerrica Benton's holographic computer transforms her into the "truly outrageous" Jem, the pink-haired singer of the band The Holograms.

In the 80's, Jem was the flagship of the world's largest toy company, Hasbro. In front of their toylines Transformers, G.I. Joe, and My Little Pony.

And the musical animated series made Jem the biggest female cartoon star of the 80's! And probably the most genuine one, since Jem was one of very few cartoons that was predominantly written by female writers. Infact, at times Jem beat all male-oriented cartoon shows in viewer ratings.

Jem clearly made a mark in the doll industry. Many brands have since been clearly inspired and also successful with similar ingredients. But Jem is her name, and no one else is the same!

Ever since the 80's, Jem has gathered a following of fans across the world, and the community of dedicated Jem fans is growing. New official Jem products are currently being released successfully, and... the 40 Year Anniversary of the Jem in 2025 is approaching, and we want even more of Jem!!!

This fansite was started in 1997, as a tribute to everything Jem, and to the people and companies that made it all happen. Here you can find in depth guides to the cartoon, reviews of the collectibles, behind the scenes material, and other informative features. And be sure to check back for updates about it all!

Rock Jem 25th Anniversary!

Making this site has been a long journey! Starting in spring, 1997. Rock Jem is the oldest Jem fansite that is still active today. Today I'd like to celebrate by announcing that the guide to the IT Jem line is complete! With nearly 7000 pictures, and still growing.

The IT Jem line grew so big it became a challenge to review. But I think the dolls are worth it! And apparently many Jem fans agree, since the line lasted so many years! And hopefully many more dolls will be released in the future, especially in 2025 when Jem is celebrating it's 40th Anniversary.

I had no idea I'd be making this site after 25 years. I'd like to dedicate the Rock Jem 25 Year Anniversary to my family and friends. And a big thanks to everyone who has visited this site over the years, and to those who have contributed.

Hopefully it can brighten up your day to take a look at all the beautiful masterpieces the Integrity Toys Jem line has consisted of over the decades.
